The Arboretum’s Halloween dog festivities are back and bigger than ever! Leashed, well-behaved dogs are welcome to join for a howling good time and costumes are encouraged!

Guests can explore the gardens through Halloween-themed and dog-focused activities, including a “Pupparazzi Photo Contest” (free entry for members, $10 for non-members), Dare Devil Dogs performances, trail etiquette information, workshops, and more. Proceeds from the photo contest go toward maintaining dog-friendly trails.

A $25 parking fee for non-members. Presented by Fred Anderson Subaru.
